There is nonradiative recombination in waveguide region owing to severe carrier leakage,which in turn reduces output power and wall-plug efficiency.In this paper,we designed a novel epitaxial structure,which suppresse...

Ga In As P layers and Ga As P/(Al) Ga In P laser diodes(LDs) have been grown on Ga As substrates by metalorganic chemical vapor deposition. The Ga In As P layer, which is lattice matched to Ga As, has an intermedi...
